Abstract
A serrated blade for an arrowhead, a crossbow bolt and/or another suitable projectile. The blade has a first blade surface that intersects with a second blade surface to form at least one cutting edge. The blade also has a mixed serration section of at least one small serration and at least one large serration. The mixed serration section is positioned adjacent to at least one cutting edge. The serrated configuration of this invention allows the blade to cut in a saw-like manner as the blade passes in a forward direction through a target material.
